Vehicle, Display Method, and Program

1. A vehicle comprising: a display device that is provided at a front side of the vehicle and is visible from the front side of the vehicle by non-occupants of the vehicle located in front of the vehicle; a measurement unit configured to measure a distance between the vehicle and a front vehicle which travels in front of the vehicle and in a same direction as the vehicle; and a display control unit configured to control the display device to selectively display content in an upright orientation and in a horizontally inverted orientation based on the distance measured by the measurement unit, the display control unit being configured to: cause the display device to display the content in the upright orientation when the front vehicle is not detected, and cause the display device to display the content in the horizontally inverted orientation when the front vehicle is detected and the distance measured by the measurement unit is less than or equal to a predetermined threshold.

2. The vehicle according to claim 1 , further comprising a determination unit configured to determine whether there is a person facing the front of the vehicle, wherein the display control unit is configured to display the content in the horizontally inverted orientation regardless of whether the distance measured by the measurement unit is greater than, equal to or less than the predetermined threshold when the front vehicle is detected and the determination unit determines that there is no person facing the front of the vehicle.

3. The vehicle according to claim 1 , wherein the display control unit is configured to additionally change a size of the content that is displayed based on the distance measured by the measurement unit.

4. The vehicle according to claim 1 , wherein the content that is displayed includes text.

5. The vehicle according to claim 1 , further comprising a determination unit configured to determine whether there is a person facing the front of the vehicle, wherein the display control unit is configured to cause the display device to display the content in the upright orientation when the front vehicle is detected, the distance measured by the measurement unit is greater than the predetermined threshold, and the determination unit determines that there is the person facing the front of the vehicle.

6. A display method of causing a vehicle including a display device that is provided at a front side of the vehicle and is visible from the front side of the vehicle by non-occupants of the vehicle located in front of the vehicle to perform: a measuring process of measuring a distance between the vehicle and a front vehicle which travels in front of the vehicle and in a same direction as the vehicle; and a display process of controlling the display device to selectively display content in an upright orientation and in a horizontally inverted orientation based on the distance measured by the measuring process, the display process: causing the display device to display the content in the upright orientation when the front vehicle is not detected, and causing the display device to display the content in the horizontally inverted orientation when the front vehicle is detected and the distance measured by the measuring process is less than or equal to a predetermined threshold.

7. The display method according to claim 6 , wherein the vehicle further performs: a determining process of determining whether there is a person facing the front of the vehicle, wherein the display process displays the content in the horizontally inverted orientation regardless of whether the distance measured by the measuring process is greater than, equal to or less than the predetermined threshold when the front vehicle is detected and the determining process determines that there is no person facing the front of the vehicle.

8. The display method according to claim 6 , wherein the vehicle further performs: a determining process of determining whether there is a person facing the front of the vehicle, wherein the display process causes the display device to display the content in the upright orientation when the front vehicle is detected, the distance measured by the measuring process is greater than the predetermined threshold, and the determining process determines that there is the person facing the front of the vehicle.

9. A non-transitory computer-readable recording medium on which is recorded a program that, when executed by a computer, causes a vehicle including a display device that is provided at a front side of the vehicle and is visible from the front side of the vehicle by non-occupants of the vehicle located in front of the vehicle to perform: a measuring process of measuring a distance between the vehicle and a front vehicle which travels in front of the vehicle and in a same direction as the vehicle; and a display process of controlling the display device to selectively display content in an upright orientation and in a horizontally inverted orientation based on the distance measured by the measuring process, the display process: causing the display device to display the content in the upright orientation when the front vehicle is not detected, and causing the display device to display the content in the horizontally inverted orientation when the front vehicle is detected and the distance measured by the measuring process is less than or equal to a predetermined threshold.

10. The non-transitory computer-readable recording medium according to claim 9 , wherein the program further causes the vehicle to perform: a determining process of determining whether there is a person facing the front of the vehicle, wherein the display process displays the content in the horizontally inverted orientation regardless of whether the distance measured by the measuring process is greater than, equal to or less than the predetermined threshold when the front vehicle is detected and the determining process determines that there is no person facing the front of the vehicle.

11. The non-transitory computer-readable recording medium according to claim 9 , wherein the program further causes the vehicle to perform: a determining process of determining whether there is a person facing the front of the vehicle, wherein the display process causes the display device to display the content in the upright orientation when the front vehicle is detected, the distance measured by the measuring process is greater than the predetermined threshold, and the determining process determines that there is the person facing the front of the vehicle.
